Abstract

La presente invención se relaciona con el campo del procesamiento de imágenes. En especial, la invención trata con la mejora de la predicción de un bloque de una imagen cuando se codifica o decodifica. Un método de decodificación de un bloque de una imagen, que comprende: obtener un parámetro de indicación para un bloque de codificación actual. El parámetro de indicación representa si una predicción de hipótesis múltiples se aplica al bloque de codificación actual; Cuando el parámetro de indicación representa que la predicción de hipótesis múltiples se aplica al bloque de codificación actual; decodificar el bloque de codificación actual de acuerdo con un modo plano.The present invention relates to the field of image processing. In particular, the invention deals with improving the prediction of a block of an image when it is encoded or decoded. A method of decoding a block of an image, comprising: obtaining an indication parameter for a current encoding block. The flag parameter represents whether a multi-hypothesis prediction applies to the current coding block; Where the flag parameter represents that the multi-hypothesis prediction applies to the current coding block; decode the current coding block according to a flat mode.
